項(xiàng)目背景分析
中海石油天野化工( 集團(tuán)) 有限責(zé)任公司現(xiàn)有1 套年產(chǎn) 300kt 合成氨、 520kt 尿素生產(chǎn)裝置, 1 套年產(chǎn)200kt 甲醇生產(chǎn)裝置。其中, 尿素裝置尿素溶液從造粒塔冷卻后形成的尿素顆粒經(jīng)皮帶系統(tǒng)輸送到散料庫(kù), 再經(jīng)皮帶系統(tǒng)輸送到包裝樓進(jìn)行包裝, 通過輸送皮帶送往站臺(tái)裝車。
原有的皮帶控制系統(tǒng)電路都是相當(dāng)復(fù)雜的老式繼電回路, 加上運(yùn)行時(shí)間已達(dá)十多年, 故障發(fā)生率很高, 一旦發(fā)生故障需用很長(zhǎng)時(shí)間來查找和排除故障點(diǎn), 給檢修和維護(hù)帶來很大不便。
隨著 PLC 在工業(yè)控制中的應(yīng)用越來越廣泛,PLC 技術(shù)也越來越成熟, 現(xiàn)已將原有的控制電路改造成由 PLC可編程控制的電路, 來改變目前輸送系統(tǒng)存在的問題。
